[PATCH v3 0/3] THP Shrinker

[PATCH v3 0/3] THP Shrinker

[alexlzhu]

From: Alexander Zhu <alexlzhu@fb.com>

Transparent Hugepages use a larger page size of 2MB in comparison to
normal sized pages that are 4kb. A larger page size allows for fewer TLB
cache misses and thus more efficient use of the CPU. Using a larger page
size also results in more memory waste, which can hurt performance in some
use cases. THPs are currently enabled in the Linux Kernel by applications
in limited virtual address ranges via the madvise system call.  The THP
shrinker tries to find a balance between increased use of THPs, and
increased use of memory. It shrinks the size of memory by removing the
underutilized THPs that are identified by the thp_utilization scanner. 

In our experiments we have noticed that the least utilized THPs are almost
entirely unutilized.

Sample Output: 

Utilized[0-50]: 1331 680884
Utilized[51-101]: 9 3983
Utilized[102-152]: 3 1187
Utilized[153-203]: 0 0
Utilized[204-255]: 2 539
Utilized[256-306]: 5 1135
Utilized[307-357]: 1 192
Utilized[358-408]: 0 0
Utilized[409-459]: 1 57
Utilized[460-512]: 400 13
Last Scan Time: 223.98s
Last Scan Duration: 70.65s

Above is a sample obtained from one of our test machines when THP is always
enabled. Of the 1331 THPs in this thp_utilization sample that have from
0-50 utilized subpages, we see that there are 680884 free pages. This
comes out to 680884 / (512 * 1331) = 99.91% zero pages in the least
utilized bucket. This represents 680884 * 4KB = 2.7GB memory waste.

Also note that the vast majority of pages are either in the least utilized
[0-50] or most utilized [460-512] buckets. The least utilized THPs are 
responsible for almost all of the memory waste when THP is always 
enabled. Thus by clearing out THPs in the lowest utilization bucket
we extract most of the improvement in CPU efficiency. We have seen 
similar results on our production hosts.

This patchset introduces the THP shrinker we have developed to identify
and split the least utilized THPs. It includes the thp_utilization 
changes that groups anonymous THPs into buckets, the split_huge_page()
changes that identify and zap zero 4KB pages within THPs and the shrinker
changes. It should be noted that the split_huge_page() changes are based
off previous work done by Yu Zhao. 

In the future, we intend to allow additional tuning to the shrinker
based on workload depending on CPU/IO/Memory pressure and the 
amount of anonymous memory. The long term goal is to eventually always 
enable THP for all applications and deprecate madvise entirely.

In production we thus far have observed 2-3% reduction in overall cpu
usage on stateless web servers when THP is always enabled.

[PATCH v3 1/3] mm: add thp_utilization metrics to debugfs

[alexlzhu]

From: Alexander Zhu <alexlzhu@fb.com>

This change introduces a tool that scans through all of physical
memory for anonymous THPs and groups them into buckets based
on utilization. It also includes an interface under
/sys/kernel/debug/thp_utilization.

Sample Output:

Utilized[0-50]: 1331 680884
Utilized[51-101]: 9 3983
Utilized[102-152]: 3 1187
Utilized[153-203]: 0 0
Utilized[204-255]: 2 539
Utilized[256-306]: 5 1135
Utilized[307-357]: 1 192
Utilized[358-408]: 0 0
Utilized[409-459]: 1 57
Utilized[460-512]: 400 13
Last Scan Time: 223.98s
Last Scan Duration: 70.65s

This indicates that there are 1331 THPs that have between 0 and 50
utilized (non zero) pages. In total there are 680884 zero pages in
this utilization bucket. THPs in the [0-50] bucket compose 76% of total
THPs, and are responsible for 99% of total zero pages across all
THPs. In other words, the least utilized THPs are responsible for almost
all of the memory waste when THP is always enabled. Similar results
have been observed across production workloads.

The last two lines indicate the timestamp and duration of the most recent
scan through all of physical memory. Here we see that the last scan
occurred 223.98 seconds after boot time and took 70.65 seconds.

Utilization of a THP is defined as the percentage of nonzero
pages in the THP. The worker thread will scan through all
of physical memory and obtain utilization of all anonymous
THPs. It will gather this information by periodically scanning
through all of physical memory for anonymous THPs, group them
into buckets based on utilization, and report utilization
information through debugfs under /sys/kernel/debug/thp_utilization.

-reversed ordering of is_transparent_hugepage and PageAnon in is_anon_transparent_hugepage, page->mapping is only meaningful for user pages

RFC to v1
-Refactored out the code to obtain the thp_utilization_bucket, as that now has to be used in multiple places.

[PATCH v3 2/3] mm: changes to split_huge_page() to free zero filled tail pages

[alexlzhu]

From: Alexander Zhu <alexlzhu@fb.com>

Currently, when /sys/kernel/mm/transparent_hugepage/enabled=always is set
there are a large number of transparent hugepages that are almost entirely
zero filled.  This is mentioned in a number of previous patchsets
including:
https://lore.kernel.org/all/20210731063938.1391602-1-yuzhao@google.com/
https://lore.kernel.org/all/
1635422215-99394-1-git-send-email-ningzhang@linux.alibaba.com/

Currently, split_huge_page() does not have a way to identify zero filled
pages within the THP. Thus these zero pages get remapped and continue to
create memory waste. In this patch, we identify and free tail pages that
are zero filled in split_huge_page(). In this way, we avoid mapping these
pages back into page table entries and can free up unused memory within
THPs. This is based off the previously mentioned patchset by Yu Zhao.
However, we chose to free anonymous zero tail pages whenever they are
encountered instead of only on reclaim or migration.

We also add self tests to verify the RssAnon value to make sure zero
pages are not remapped except in the case of userfaultfd. In the case
of userfaultfd we remap to the shared zero page, similar to what is
done by KSM.

Signed-off-by: Alexander Zhu <alexlzhu@fb.com>
---
v1 to v2
-Modified split_huge_page self test based off more recent changes. 

RFC to v1
-Added support to map to the read only zero page when splitting a THP registered with userfaultfd. Also added a self test to verify that this is working.
-Only trigger the unmap_clean/zap in split_huge_page on anonymous THPs. We cannot zap zero pages for file THPs.

[PATCH v3 3/3] mm: THP low utilization shrinker

[alexlzhu]

From: Alexander Zhu <alexlzhu@fb.com>

This patch introduces a shrinker that will remove THPs in the lowest
utilization bucket. As previously mentioned, we have observed that
almost all of the memory waste when THPs are always enabled
is contained in the lowest utilization bucket. The shrinker will
add these THPs to a list_lru and split anonymous THPs based off
information from kswapd. It requires the changes from
thp_utilization to identify the least utilized THPs, and the
changes to split_huge_page to identify and free zero pages
within THPs.

Signed-off-by: Alexander Zhu <alexlzhu@fb.com>
---
v2 to v3
-put_page() after trylock_page in low_util_free_page. put() to be called after get() call 
-removed spin_unlock_irq in low_util_free_page above LRU_SKIP. There was a double unlock.    
-moved spin_unlock_irq() to below list_lru_isolate() in low_util_free_page. This is to shorten the critical section.
-moved lock_page in add_underutilized_thp such that we only lock when allocating and adding to the list_lru  
-removed list_lru_alloc in list_lru_add_page and list_lru_delete_page as these are no longer needed. 

v1 to v2
-Changed lru_lock to be irq safe. Added irq_save and restore around list_lru adds/deletes.
-Changed low_util_free_page() to trylock the page, and if it fails, unlock lru_lock and return LRU_SKIP. This is to avoid deadlock between reclaim, which calls split_huge_page() and the THP Shrinker
-Changed low_util_free_page() to unlock lru_lock, split_huge_page, then lock lru_lock. This way split_huge_page is not called with the lru_lock held. That leads to deadlock as split_huge_page calls on_each_cpu_mask 
-Changed list_lru_shrink_walk to list_lru_shrink_walk_irq. 

RFC to v1
-Remove all THPs that are not in the top utilization bucket. This is what we have found to perform the best in production testing, we have found that there are an almost trivial number of THPs in the middle range of buckets that account for most of the memory waste. 
-Added check for THP utilization prior to split_huge_page for the THP Shrinker. This is to account for THPs that move to the top bucket, but were underutilized at the time they were added to the list_lru. 
-Multiply the shrink_count and scan_count by HPAGE_PMD_NR. This is because a THP is 512 pages, and should count as 512 objects in reclaim. This way reclaim is triggered at a more appropriate frequency than in the RFC.

debugfs as a primary interface? Looks wrong to me.

I don't follow what is going on. thp_scan vs thp_scan_debugfs looks
confusing.

pfn_valid() + pfn_to_page() has to be replaced to pfn_to_online_page().

lru_lock would be a tad more descriptive.

You should already be getting head pages here since you walk the pfns
in huge page steps. It would be better to do pfn_folio() in the
scanner and just work with folios here throughout.

The indentation is a little messed up.

The trylock could use a comment:

Oof, fatfingered send vs postpone. Here is the rest ;)

The re-lock also needs to be unconditional, or you'll get a double
unlock in the not-split case.

A brief comment would be useful:

Here as well:

Why is that?

And here:

	/* Stabilize page->memcg to allocate and add to the same list */

The testbot pointed this out already, but this allocation call needs
an #ifdef CONFIG_MEMCG_KMEM guard.

I’ll consider it. Do you think this is necessary? It is huge page related, but huge_memory has a lot of code already.

Where would you recommend? We had initially put it under /proc, and then moved to debugfs.

The reason we have two is that one of them is used for debugfs if ‘cat /sys/kernel/debug/thp_utilization’ is called. 
The other is used to keep track of the current scan.

I had considered that at the time but memchr_inv() used here would return the address of the first nonzero byte. 
Here we are trying to find the utilization percentage of the THP. I do not believe memchr_inv() would be less code
as compared what we do here.

Scanning 256 PFNs per second is just what we have found to not have any noticeable effect on our hosts.

In addition to use pfn_to_online_page() as pointed out by Kirill, do we
need to consider memory hot-remove too?  Per my understanding, the page
may be offlined under us while we are scanning, so we need to use
get/put_online_mems() to enclose the code to access the page or increase
the page count.  But I don't find this is considered in some existing
code such as split_huge_pages_all().

Just use

        pfn_end = round_up(zone_end_pfn(thp_scan.scan_zone), HPAGE_PMD_NR);

But why round_up()?  Just use zone_end_pfn() is sufficient?

In general, I think it's better to use library functions if possible.
memchar_inv() can be used here to check whether the subpage is all zero
via checking whether NULL is return.

memchar_inv() isn't perfect for your purpose, but your code doesn't look
like highly optimized too.  Is it necessary to add another library
function to check whether the contents of a range of memory are all
zero?  Then we can optimize the implementation.

Better to show some performance data here.  For example, ftrace
callgraph can be used to collect the run time of
thp_utilization_workfn() on a system full of THP.

And, it will take about 512s to scan all memory on a system with 256 GB
memory.  This appears long too.

Why do we need clear PTE and flush TLB again?  If my understanding were
correct, the TLB has been flushed when unmapping the page.  Otherwise,
we need to flush TLB before checking whether the page is all-zero.

If my understanding were correct, the THP will be considered under
utilized if utilization percentage < 90%.  Right?  If so, I thought
something like utilization percentage < 50% appears more appropriate.

Because we haven't get reference of the page, the page may be split or
free under us, so VM_BUG_ON_PAGE() here may be triggered wrongly?

is_huge_zero_page() check can be done in thp_util_scan() too?

It appears that only 2 lines are different from list_lru_add().  Is it
possible for us to share code?  For example, add another flag for
page_memcg() case?

Yes, < 90%. That is just the best number we have found so far from our experiments, as it seems almost all THPs are <10% utilized or >90% utilized . There are an almost trivial number of pages in between.

I believe there are 4 lines. The page_to_nid(page) and the spin_lock_irqsave/restore. 
It was implemented this way as we found we needed to take a page as a parameter and obtain the node id from
the page. This is because the THP is not necessarily a slab object, as the list_lru_add/delete code assumes. 

Also, there is a potential deadlock when split_huge_page is called from reclaim and when split_huge_page is called 
by the THP Shrinker, which is why we need irqsave/restore. 

I though this would be cleaner than attempting to shared code with list_lru_add/delete. Only the shrinker makes use of this. 
All other use cases assume slab objects.

So, even if it's <= 10%, the results will be almost best.  Yes?  If so,
why use 90%?  Which is appears too extreme.

Can you provide more details on this?  If it's necessary, I think it should be OK to use irqsave/restore.

> I though this would be cleaner than attempting to shared code with list_lru_add/delete. Only the shrinker makes use of this. 
> All other use cases assume slab objects.

Not only for slab objects now.  The original code works for slab and
normal page.  Which is controlled by list_lru->memcg_aware.  You can add
another flag for your new use case, or refactor it to use a function
pointer.

There is an ABBA deadlock between reclaim and the THP shrinker where one waits for the page lock and the other waits for the 
list_lru lock. There is another deadlock where free_transhuge_page interrupts the THP shrinker while it is splitting THPs (has the
list_lru lock) and then acquires the same list_lru lock (self deadlock). These happened in our prod experiments. 
I do believe irqsave/restore is necessary.

Per my understanding, when we hold list_lru lock, we only use
trylock_page() and backoff if we fail to acquire the page lock.  So it
appears that we are safe here?  If not, can you provide the detailed
race condition information, for example actions on different CPUs?

Got it.  We may use list_lru lock inside IRQ handler when free pages.  I
think this information is good for code comments or patch description.

The ABBA deadlock was the reason we added this try lock_page(). It is safe now, was not safe in v3.

Sounds good! I’ll add some comments to make that more clear.
